Problems solved by technology

[0006] In addition, there are some other patents or articles disclosing film sticking devices and methods. However, in the prior art, flat films are used to directly stick to products. This method is not suitable for film sticking of 3D products, because : The shape of the 3D product is not flat, and if the flat film is directly pasted on the 3D product without bending, it will cause serious defects (such as bubbles, wrinkles, OCA damage, etc.), resulting in low product qualification rate and low product production efficiency

Embodiment 1

[0036] see figure 1 , a carrier film for 3D products, comprising a carrier film body 1, the carrier film body 1 includes a first film layer 1.1, an adhesive layer 1.2 and a second film layer 1.3 stacked in sequence, the first film layer 1.1 , the outer dimensions of the adhesive layer 1.2 and the second film layer 1.3 are the same.

[0037] The middle position of the second film layer 1.3 is provided with a hollow part 1.31 that matches the outline of the 3D product to be pasted after unfolding (the area of ​​the hollow part is slightly larger than that of the 3D product after unfolding, for example, the surrounding area of ​​the hollow part is larger than that of the 3D product. The four sides are 0.10-0.15mm wide, and the four corners are larger, these parameters are determined according to the actual situation).

[0038] The material of the first film layer 1.1 and the second film layer 1.3 is polyethylene terephthalate; the material of the adhesive layer 1.2 is acid-free ...

Embodiment 2

[0044] A composite film for 3D products, see details figure 2 , this composite film includes the carrier film for 3D products in Example 1 and the independently set diaphragm 2 .

[0045] The membrane 2 is arranged in the hollow part 1.31 of the second membrane layer 1.3, the back of the membrane 2 is attached to the adhesive layer 1.2, and the front of the membrane 2 is provided with a protective layer.

[0046] The specific process of applying the above-mentioned composite film for 3D products to film includes the following steps:

[0047] The first step, making a carrier film for 3D products; laminating the diaphragm 2 with the carrier film for 3D products to obtain a composite film for 3D products;

[0048] The second step is to position the 3D product with the composite film through the positioning through hole 3 on it and the positioning column on the fixture;

[0049] The third step is to fix the 3D product on the fixture with a composite film (here it can be fixed b...

Abstract

The invention provides a bearing film for a 3D product. The bearing film comprises a bearing film body, wherein the bearing film body comprises a first film layer, a bonding layer and a second film layer which are sequentially superposed; and a hollow part which is matched with the contour of a to-be-laminated 3D product is arranged on the second film layer. The bearing film is simple in integralstructure and is convenient to manufacture. The invention further discloses a composite film for a 3D product, and the composite film comprises the bearing film for the 3D product and an independentlyarranged film sheet; the film sheet is arranged on the hollow part of the second film layer; the back surface of the film sheet is bonded with the bonding layer; a protective layer is arranged on thefront surface of the film sheet, so that the 3D product can be laminated with the film very well; the bonding layer is designed by adopting an unique material, and the bearing film for the 3D productis easily taken off after film laminating, and residues are avoided, so that the yield of the film-laminated 3D product is high. The invention further discloses a method for laminating the compositefilm for the 3D product, and the method is simple in process step, easily controls process parameters, and is high in product yield.

Description

technical field [0001] The invention relates to the technical field of film sticking, in particular to a carrier film for 3D products, a composite film including the carrier film, and a film sticking method. Background technique [0002] With the continuous development of technology, people have higher and higher requirements for the quality of products, especially electronic products that are used more daily. Filming electronic products is a widely used method at present. In the prior art, the film sticking device and the method for sticking the film are as follows: [0003] The invention application with the application number of 201610340254.7 discloses a film laminating machine, specifically: comprising a floating knife plate and a profiling guide rail, the floating knife plate includes a knife plate fixing frame and a film peeling blade, and the blade fixing frame is rotatably fixed on the film On the machine, the peeling knife plate is fixed on the knife plate fixing...
